SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Debugging C/C++ applications when static analysis is unreliable.

Core Features & Use Cases

  • Crash analysis: pinpoint crash origins and assess impact.
  • Memory debugging: inspect memory, variables, and stack traces to diagnose corruption.
  • Controlled execution: run, pause, and timebox operations to avoid hangs.
  • Breakpoint-driven workflows: set breakpoints, step through code, and inspect state across sessions.
  • Multi-session support: manage parallel debugging tasks for complex scenarios.

Quick Start

Use the lldb-debug skill to load an executable, set breakpoints, and launch with explicit timeouts to observe runtime behavior safely.

FAQPage Schema
How do I debug a C/C++ application when static analysis is unreliable?▼

You can debug C/C++ applications using LLDB-guided workflows that support crash analysis, memory bug diagnosis, breakpoints, and core-dump analysis. This approach provides deterministic execution with timeouts and state polling to safely observe runtime behavior.

What is the best way to diagnose memory corruption and crashes in C/C++?▼

Diagnose memory corruption and crashes by inspecting memory, variables, and stack traces with LLDB. The debugger pinpoints crash origins, assesses impact, and allows you to step through code to identify exactly where memory bugs occur.

Can I run timeboxed debugging sessions to avoid application hangs?▼

Yes, you can run timeboxed debugging sessions to avoid hangs. The debugger provides controlled execution with explicit timeouts, allowing you to safely run, pause, and observe your application without risking indefinite blocking.

Does LLDB support multi-session debugging for complex scenarios?▼

LLDB supports multi-session debugging for complex scenarios, allowing you to manage parallel debugging tasks. You can maintain breakpoint-driven workflows and inspect state across multiple sessions simultaneously.

How do I analyze a core dump to find the origin of a crash?▼

Analyze a core dump by loading it into the debugger to inspect stack traces and application state at the moment of failure. This pinpoints the crash origin and helps assess the impact of the error.

What are the limitations of using LLDB for C/C++ memory diagnostics?▼

LLDB requires deterministic workflows to manage timeouts and state polling safely. While it excels at inspecting memory and variables, complex memory corruption may still need controlled execution and breakpoint-driven workflows to avoid hangs.
